Hong Kong · Software engineering and technical consulting
Sweet Intelligence Limited is a technology research and development company with its office in Central, Hong Kong. We write mobile, web and backend software, we build LLM agents on client data, and we advise engineering teams on architecture, code quality and technical risk.
Services
Four lines of work, each delivered by the engineers who scoped it. Every engagement produces running software in a repository the client owns, together with the documentation needed to operate it.
01
We build iOS and Android applications and the web applications that sit alongside them. The work covers interface implementation, offline and sync behaviour, release builds, and submission to the App Store and Google Play.
Business logic is covered by automated tests before a build reaches a store.
02
We build backend services, APIs and data pipelines, and we integrate them with the systems a client already runs. Internal platforms, scheduled jobs, queues and reporting databases are part of the same scope.
Schema migrations are written to run forwards and to be reversed if a release is rolled back.
03
We build LLM agents and copilots that retrieve from client data, call internal tools, and return the work to a named person at defined review points. Each agent ships with an evaluation harness and a fixed test set, so a prompt or model change can be measured before it goes live.
Guardrails, rate limits and logging of prompts, tool calls and outputs are part of the build.
04
We review architecture and code, and we build prototypes to settle technical questions that a document cannot answer. We also carry out technical due diligence on software a client is acquiring or inheriting.
For longer engagements we place engineers inside a client team for a fixed period to work on that team's own backlog.
Delivery
Projects run in short iterations, and each iteration finishes with a build a client can open and use. The durations below are the estimates we work to, and each one is confirmed in the scoped specification.
STAGE 01
We read the existing code and data, and we talk to the people who maintain them, so that constraints, integrations and unknowns are written down rather than assumed.
The output is a scoped specification with an estimate for each component.
Typically 2 weeks
STAGE 02
We agree the stack, the data model and the interfaces between services, then stand up a deployable skeleton with continuous integration, environments and logging from the first commit.
A staging environment is live and reachable by the client at the end of this stage.
2 to 3 weeks
STAGE 03
Features are built in two week iterations, each ending with a deployment to staging and a written changelog of what changed and what is still open.
Code review and the automated test suite run on every pull request before it is merged.
6 to 10 weeks to a first release
STAGE 04
We run the production release, watch the first weeks of real traffic, and fix what the logs and error reports show.
Hand-over is complete once an engineer on the client side has deployed the system themselves using the runbook we wrote.
2 weeks, with support by agreement
Tools and practice
The team works across mobile, web, backend and model tooling, and chooses the stack that fits the systems a client already operates. The list below covers the technologies and practices we work with regularly.
Where a client already runs a different stack, we work inside it and say so in the estimate.
